<h3>About SeaMule</h3><p>Based in Madeira Beach, Florida — the heart of Florida's Gulf Coast boating community — SeaMule is a marine solutions brand built around one guiding philosophy: life on the water should be effortless. From weekend anglers to seasoned offshore captains, SeaMule designs products that eliminate the tedious side of boat ownership so you can spend more time doing what you love.</p><h3>The Flushmaster: Redefining Outboard Engine Care</h3><p>SeaMule's flagship innovation is the <a href="/18624-seamule-engine-flushes-201925">Flushmaster Outboard Engine Flush System</a> — widely recognized as the world's first portable, automated outboard flushing device for single and multi-engine boats. Flushing outboard motors after saltwater use is one of the most critical maintenance habits a boat owner can develop, yet it has traditionally been a time-consuming, hands-on chore. The Flushmaster changes that equation entirely.</p><p>The device handles up to four outboard motors sequentially, flushing each one for a pre-programmed duration before automatically shutting off and blocking the water flow — no babysitting required. Powered by just three AA batteries, it connects easily to any standard freshwater source and cycles through every motor in order, ensuring thorough cleaning without the owner having to stay present.</p><ul><li><strong>IP67 waterproof certified</strong> — built to withstand harsh marine environments, including rain, spray, and accidental submersion</li><li><strong>Compatible with four-stroke outboards</strong> across major brands including Mercury, Yamaha, Suzuki, and Honda</li><li><strong>Available in 2-outlet and 4-outlet configurations</strong> with multiple hose length options to fit a wide range of boat setups</li><li><strong>Auto shut-off</strong> once all motors are flushed, conserving water and freeing up your time</li><li><strong>Included 1-year warranty</strong> for peace of mind</li></ul><h3>The Complete Flush System</h3><p>SeaMule doesn't stop at the Flushmaster controller. The brand also offers Flush Port Quick Connects — purpose-built connectors that permanently replace OEM flush ports on Mercury, Yamaha, Suzuki, and Honda engines. Together, the Flushmaster and Quick Connects form a comprehensive <a href="/18624-seamule-engine-flushes-200369">outboard engine flush solution</a> that makes connecting hoses a one-handed, tool-free process. Additional Flush Hose Kits, a Housing Cradle, Portable Storage Bag, and a PVC Piling Plumbing Kit round out the ecosystem for boaters who want a fully integrated setup.</p><h3>Built for the Water, Designed for Convenience</h3><p>Every SeaMule product is engineered to hold up in the demanding marine environment — UV-resistant, weatherproof, and constructed from materials chosen for long-term durability on the water. The brand's commitment to sustainable, eco-conscious materials reflects an understanding that the boating community depends on healthy waterways. Whether you're docked at a marina, tied up at a piling, or back in the driveway after a long day offshore, SeaMule's solutions are designed to fit naturally into your post-trip routine.</p>

Product Details

The SeaMule Flushmaster Quick Connect Flush Port is specifically designed for Mercury outboards, providing a hassle-free solution for engine flushing and maintenance. This innovative flush port eliminates common frustrations like stuck caps, stripped threads, and time-consuming hose connections, making post-outing maintenance faster and more reliable.

Key Features:

  • Quick-connect design for fast, tool-free hose attachment
  • Engineered specifically for Mercury outboard motors
  • Eliminates stuck caps and cross-threaded connections
  • Durable white finish resistant to marine environments
  • Simplifies routine engine flushing to remove salt, sand, and debris
  • Secure connection prevents leaks during flushing operations

Regular flushing with the SeaMule Flushmaster helps extend engine life by removing corrosive saltwater and contaminants from your outboard's cooling system. The quick-connect system saves valuable time at the dock or ramp, allowing you to complete proper engine maintenance in seconds rather than minutes.

Great! Equal to any

The website was very easy to use and had the prop I was looking for.

Easy and fast!

Great if I order again I will be using the same website again. Thanks

Great prices and a surprisingly fast delivery, which despite choosing the most economic choice (2-14 days), I received the items in 5 days - saved more than half in shipping. Great all around experience and great product extremely well packaged. Thank you, folks!
